How to make son feel better?

Question

My son who is studying in boys only school, is champion in tennis in his school.He is 16.He thought he is best in tennis but I knew he isnt.He believed no girl can beat him.2 days before my friend as well as his english madam [same as my age] visited my home.At one point of talking she said that tennis playrs in her school are not good.My son argued with her and he invited her to play.She accepted it and game starts in our compound.I remebered she was one among better players in our school.But that was2o years before and she never used to play it nowadays so i thought my son would win.But score was 6-0 6-0 in favour of her.Then he said game was out of 5 sets and until then he was checking her game.Game restarts again but in first game itself one of her powershot got his testicles.He collapsed into ground.He cried and we helped him to get into his room.She asked him to keep icepack.Still now he is walking with open legs.he is too embarrassed to face me.He also didnt want to go to school.How could I change him
